2017 Map of Bottleneck Lake

About this map

Craters of the Moon National Monument dominates this high-desert landscape in Minidoka County, preserving a complex volcanic terrain of lava flows and cinder cones. The map details a series of water features scattered across this arid environment, including Bottleneck Lake, Three Forks Lake, and S End Lake. Man-made water management is evident through features like Pronghorn Reservoir and Lower Thumb Reservoir, which suggest the historical and ongoing efforts to capture runoff in this drainage-sparse region of Idaho. The boundary lines for T4S R24E and T5S R24E reveal the systematic grid of the Public Land Survey System as it overlays the irregular volcanic topography. In the southeastern corner, Larkspur Park provides a localized point of interest amidst the expansive monument grounds.
